I think 5160 differential hardened at 1/4" will be plenty-given that when I do the bend test on a 1/4" 5160 test blade 8" long I have to put a 3' breaker bar on it, and I'm scrambling a bit...hilts give out looooong before the blade in my experience...i like where this is going
Thanks for your input on this JW. While some khuks (or any knife type) are obviously meant for heavier work than others, 1/4" of steel, especially differentially HT'd, should be capable of quite a bit of work. This one has definitely lightened the load a bunch with a chirra, so YMMV, but generally speaking I think JW is correct.
FYI - I know what dui chirra and tin chirra mean, but I didn't know what "Yek Chirra" means, so I emailed Yangdu. She responded: "Yek means 1 in Nepalese language and chirra means fuller
This knife has single fuller on both side of blade and this is why Thamar kami name this knife Yek chirra"
I think we would normally call it an Ang Khola. This one differs from HI's normal AKs in looks and style, so, maybe Yek Chirra is a way to differentiate from the standard model.
This guy is knocking it out of the park with these traditional flavored khuks. Stunning!
Man, I couldn't agree more. I believe I've seen his work before (I may even have one of his khuks

) and am sure (I'd be willing to bet two yaks and yeti scalp

) this model is based on an actual antique/vintage ang khola he's used as a model, with one change being the addition of a standard butt plate. His dui chirra is almost a dead ringer for a really nice WWII AK, except with an added chirra and extra 1/2".
Kamis seem to come and go with the wind, unfortunately, but luckily this guy has returned with some new ideas and mad skills. HI gave him his start, so it maybe Karma coming full-circle. I believe there is a strong market for these traditional khuks, and boy is this guy nailing them! I'm curious to see some testing and see how the heat treat is with the new kami. As great as these look, they're probably even better users for reasonable work. This 18", 16 oz. AK may be a dedicated man cutter (I don't know how the kami even made it that light, but love it!), but that DC from the other day at 23 oz. should be an outstanding all-around blade. I bet the other kamis are going to be envious. I can't wait to see some reviews. I would keep this guy away from the other models so this traditional line doesn't get diluted and gain weight. I really believe HI will please a lot of people selling both types. Congrats on the new kami. I think he's a game changer:thumbup:
